How is zeroing typically performed for the M4/M16, and what does a 25-meter zero enable?

• A. Fire a controlled group at 25 meters and adjust sights until POI matches POA.
• B. Zero at 50 meters with a single shot.
• C. Zero at 100 meters using ballistic matching.
• D. Zero at 25 meters and verify that POI matches POA; provides reliable close-range accuracy and a basis for longer-range adjustments.

Answer: (D)

Zeroing is about aligning the sights so the bullet hits where you intend to. For the M4/M16, the standard method is to zero at 25 meters: you adjust the sights until the point of impact at 25 meters matches the point of aim. This gives reliable close-range accuracy because your sight picture and the actual hit are synchronized at a distance you can quickly verify. It also provides a solid baseline for longer-range use, since you can apply ballistic data or holdovers from that 25-meter reference to anticipate how the bullet will drift with distance. In short, a 25-meter zero makes you confident about near-term accuracy while giving a practical starting point for extending accuracy to longer ranges.
